Low-Voltage Disconnect Switch Safeguards Vehicle Batteries

The model 48513 SureStart low-voltage disconnect (LVD) switch electronically senses battery voltage and conserves starting power by disconnecting non-critical loads, prolonging battery life by preventing battery damage due to excessive discharge. This switch is suited for utility and delivery vehicles, as well as vehicles with ancillary on-board equipment, such as snowplows, hoists, pumps, and floodlights, as well as in-cab amenities such as air conditioning. The switch has a rating of 100 A at 12 V or 24 V dc. Its service life exceeds 1 million on/off cycles; it also features a manual override that allows users to connect or disconnect the switch when needed, regardless of voltage. The compact 4.5 x 4 x 4.27-in. switch is easily installed into any vehicle. It does not require a separate solenoid to control high current, increasing reliability and simplifying installation. The switch’s resistance to moisture, salt spray, vibration and shock make it a versatile device that can be implemented into any vehicle or environment. COLE HERSEE CO., Boston, MA. (617) 268-2100.
